The Lyon County Sheriff’s Office Investigative Division is made up of two Investigators who investigate major crimes such as sexual assaults, burglaries, child abuse, physical assaults, homicide, financial and internet crimes, as well as assisting the patrol deputies when necessary. The Investigators will follow up on reports taken by patrol deputies. They also receive reports from Family Services and the Lyon County Attorney’s Office, and handle assignments directed by the Sheriff, or Sergeants. They can also assist in investigating crime scenes with photographs, fingerprints, and other forensic evidence. Cases that are sent to the Investigative Division by patrol deputies are reviewed by the Investigators and followed up on appropriately. If there are no leads, the case is filed as inactive. If there is additional information that surfaces the case can be reopened and investigated at such time. The Investigative Division is also in charge of undercover operations such as alcohol and tobacco stings and drug sale crimes. All background checks for hiring within the department are handled by the Investigative Division. The Investigative Division also assists with internal investigations for other agencies. If anyone is interested in leaving information on a crime that has been committed, they are encouraged to call:
